Time zone abbreviation names are buggy

[mostafa-rz]

Hi,
I tried to use getAbbreviatedName(), but it returned the wrong result. If I use the PHP timezones I will get the correct one.

// Carbon, result amt
Carbon\CarbonTimeZone::create('Europe/Athens')->getAbbreviatedName()


// PHP, result EET
$timezone = new DateTimeZone('Europe/Athens');
$dateTime = new DateTime('now', $timezone);
$abbreviation = $dateTime->format('T');

I also did some debugging, and it seems that in this line, the array returned by the $this->listAbbreviations() could contain more than one 'Europe/Athens' in different abbreviations.
